  1. 1. Comparing different methods of measuring particle size for pharmaceutical excipients

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Jiawen Wang; [2022]
    Nyckelord :particle size; comparison; Malvern analysis; Qicpic analysis; Pharmaceutical technology; Technology and Engineering;

    Sammanfattning : In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by laser diffraction analysis (Malvern wet and dry), dynamic image analysis (Qicpic), and microscopic methods (Qicpic, SEM, and light microscopy) to determine the applicability and limitations of each method, as well as to clarify their advantages and disadvantages.

  3. 2. Trådlösåterställning av industriella ljusskydd : Trådlösåterställning av ljusridåer/ljusbommar med ett öppet lasersystem

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Författare :Viktor Lindholm; [2017]
    Nyckelord :UART; laser module; solar cell; light protection; Arduino; Smart industrial; UART; lasermodul; solcell; ljusbommar ljusridåer; Arduino; smart industri;

    Sammanfattning : Ljusbommar/ljusridåer är ett vanligt säkerhetsskydd på dagens industrier, där arbete görs vid rörliga delar.  Det ställs höga säkerhetskrav på ljusbommar/ljusridåer. När ett skydd bryts behöver det återställas och detta görs vanligtvis med en tryckknapp. LÄS MER
